BTDAihupfu hwebrown brown crystalline. Nzvimbo yekunyunguduka kwechinhu ichi i218.67 ° C uye inoora pa360 ° C. Tembiricha yekubvira kwega kwega yakanyanya uye hapana kutsva kwakaonekwa. Kuwanda kwechinhu ichi i1.545Chemicalbook2g/ml, uye kumanikidzwa kwemhepo ndeye 6.53E-011Pa. Chinhu ichi chinonyunguduka zvishoma mumvura, chine logPow ye3.3. Kushandiswa kweBTDA sechikamu chepakati muindasitiri yekugadzira zvigadzirwa zvepurasitiki kana makemikari akanaka.
